Looking back through the messages, I saw this line:
> linux-ryeo:~ # modprobe snd-hda-intel
> modprobe: FATAL: Module snd-hda-intel not found.
Is this still the result? If so, you must have written *THIS*. It's damn
important.
It implies that your system is severely broken. Not only about sound.
Try to re-install the latest update kernel like:
zypper in -f kernel-desktop
Does this show any error? If this succeeds without any error, reboot. Then
retest the sound.
If the sound still doesn't appear, try again "modprobe snd-hda-intel". If this
results in the same error message, now check the following:
find /lib/modules -name 'snd*.ko'
Does this show anything?
